$PECIFICATION forming part of Letters Patent NO. 432,435, dated July 15, 1890. Application filed August 17, 1889. Serial No. 321,964. (No model.)

To all whom it vnagj concern;

Be it known that I, ELISHAPEOK, a citizen of the United States, and a resident of 'lVawaka, in the countyof Noble and State of Indiana, have in vented certain new and useful Improvements in Vindmills; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaius to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is partly a vertical central sect-ion. Fig. 2 is a view of the opposite faces of the hub-disks separated. Fig. 3 is a side View of the hub, and Figs.4 and 5 are detail views. Fig. 6 isa detail sectional view of the jointbetween thepump rod sections.

This invention relates to certain improvements in windmills; and it consists of the novel construction and combination of parts, as hereinafter set forth.

In the embodiment of my invention I provide the tower A, upon the upper end of which is secured the turn-table a.

B is a wheel-casting having its lower beveled end seated and turning in the upper countersunk surface of the turn-table a. To a socket b of wheel-casting B is applied the rod carrying the rudder or supplementary vane c.

C is the wind-wheel, whose shaft 0 is suitably journaled upon the upper end of the cross-arm (Z of the wheel-casting B, one end of which shaft carries a disk or eccentric c,

-to which is connected by a pitman e the pump-rod D. The pitinan c has a wrist-pin connection with the eccentric or disk 6 and is sleeved upon a pin or projection e of the pump-rod D, said pin or projection extending out through a vertical slot 6 The wheel 0 comprises a two-part hub G and a series of angularly-arranged radial blades O which are braced in position and connected together at outwardly-diverging intervals apart by zigzag bars or braces 0 bolted to the blades a short distance inward from their outer ends.

The hub C consists of two circular plates or disks 0 The disk or plate 0 has projecting from one side a cylindric flange or rim 0 while from its opposite side projects a chambered or hollow cylindric extension 0 its open sidebeing toward the rim or flange C The chambered or hollow extension 0 terminates in anarrow or contracted passage, which is of a diameter adapted to just receive the wheel-shaft 0'. Upon this side of the plate or disk C and of slightly greater diameter than the extension C is a shallow circular chamber or recess C the inner wall of which is formed by said extension, which is provided at suitable intervals apart with lugs or projections C Radially from the outer wall of the recess or chamber 0 stands a series of grooves C. The opposite plate or disk 0 has projecting from that side facing the plate or disk C a narrow circular channel or groove 0 the inner Wall C of which has anumberof recesses or notches O WlllCll register with and receive the lugs or projections 0 and thus prevent the turning of the part or plate 0*. Also standing radially from the outer wall of the channel 0 is a series of grooves 0 which, by reason of the relation of the engagement of the notches C and lugs C therewith, range obliquely opposite to each other, thus providing for the feathering 'of the blades 0*, which they are designed to receive. 'The adjustment of the relation of the grooves to each other, in order to vary the feathering of the blades, it

is obvious, can be readily effected by shifting the notches C to others of the lugs or projections O, as may be required. The blades 0 are further braced in position by rods (1, connected to the arm or flange C of the hub of the wheel and to certain parts of the blades near their outer ends.

'lhepump-rodD is partially hollow or tubular and passes through upperandlower tubular or hollow cylindric sections B B of the wheel-casting B and a separate similar capsection f, fitting upon the upper end of said upper sect-ion B. This cap-section f rests at its lower-end upon a separate section f, fitted upon the section B, and has journaled in its extreme upper enlarged end a pulley g, over whichpasses a cordorline E. Thiscord extends from a point within easy reach of theoperator, being preferably passed through an aperor opposite end connected to the governor F, as shown, for the manipulation of the latter to take the wheel out of the wind to slacken its speed, as will be understood. The pumprod consists of two sections D D which are connected together by a flexible sliding joint, as at d, a spring (Z automatically holding the two sections in engagement, said joint comprising an enlargement (1* on the lower section D engaging a shoulder (1 on the upper section I) at its lower end. The spring (1 rests at its lower end upon a collar (l or shoulder of the lower pump-rod section, and has its upper end entering the lower hollow or tubular section B of the wheel-casting l5 and connecting with the upper pump-rod section. The lower end of the pump-rod .enters the pump-barrel h, and to one side of the latter is secured the lower end of a stout flat spring i, which serves as a fulcrum for a hand-lever j, pivoted, as at j, to the upper end of said spring. This lever carries at its forward end a sleeve 7;, pivoted, as at K, thereto, through which passes the lower end of the pump-rod D, and is adapted to engage a shoulder or collar L on the] latter, and thus normally hold the pump-rod sections 1) D in engagement against the action of the,

spring (1 :It will be observed that as the handle ofthe lever j is thrown down the collar K is elevated, and the pivot of said lever and the pivot'of the collar K being brought substantially in the same vertical plane the descent of the lower pump-rod section is prevented by the collar-K engaging thecollar K, the upper pump-rod section being unable to descend against the stress of the spring (1*. On the down together, the rosistanee'of the spring to the eompressorbeing greater than that offered by the working of the pump. This arrangement is designed to permit of stopping the pumping action of said red when it is desired to put the mill out of operation, though the wheel may be in motion.

H is the vane, the innerend of which has a short vertical shaft h, which is centered or journaled between a stud h of the wheelcast-ing l3 and a stud h on the section f above referred to. The shaft hearries a tootlrsector h, engaging a corresponding sector It on the disk-shaped portion of the governor F. Upon the return side of the vane 11 is applied, atits inner end, a stout strong spring h,which, upon the maximum return movement of the vane, is designed to engage the side of the section B of the wheel-casting B, and thus automatically to limit the movement of the vane in that direction.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s

1. In a windmill, the combination of the wind-wheel and its shaft and pitman,the twopart or sectional pump-rod, 'its sections or parts having a flexible or spring joint-connection, and the lever fulcrumed upon a spring and carrying a pivot-ed sleeve or collar which engages a shoulder or collar on the pump-rod, substantially as set forth.

2. The combination of the wind-wheel, its shaft and pitman, the wheel-casting bearin g the wind-wheel shaft, the vane, the rudder,

and the governor geared to said vane, the partially-hollowpump-rod formed in sections hav' ing a flexible joint-connection, the hand-lever f ulcrumed upon a spring and carrying a sleeve or collar engaging a shoulder upon said pump-rod, and the cord or line connectedto the governor and passed through the pumprod and over a pulley in the hollow cap-section, substantially as specified.

In testimony whereof I afiix my signature in presence of two witnesses.
